Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart of a method for excluding fingerprints of a host and related persons in a scene according to an embodiment of the present invention. As shown in fig. 1, the method includes:
when the finger and palm prints of a case site need to be checked, a client firstly creates a checking task, wherein the checking task corresponds to the case one by one; after the investigation task is established, the case identification corresponding to the investigation task is generated at the same time and is used for representing the case corresponding to the investigation task.
And after establishing the troubleshooting task, the client sends the case identification to the server. The actual troubleshooting task is executed by the server; the number of the clients is one or more, that is, the server can serve a plurality of clients in a parallel manner.
after receiving the case identification sent by the client, the server side knows that the client has newly established a troubleshooting task, establishes a storage directory according to the case identification and is used for storing a finger and palm print corresponding to the case identification and/or comparing a troubleshooting result; meanwhile, a troubleshooting engine (a service or a program for comparison and troubleshooting) is started, and preparation for executing a troubleshooting task is made.
103, adding field finger and palm prints and ten finger and palm prints to the server by the client, wherein the field finger and palm prints are acquired at a case scene, the ten finger and palm prints are acquired of a host and related persons, and the field finger and palm prints and the ten finger and palm prints carry corresponding finger and palm print identifiers and case identifiers;
the live finger print and the ten-finger print can be obtained from an external server by using a data interface. The on-site finger-palm prints refer to finger-palm prints acquired in a case scene, and the ten-finger-palm prints refer to collected owner and finger-palm prints of related people; the field finger palm prints and the ten-finger palm prints can be collected by image collecting equipment and then stored in the external server.
And after the client acquires the field palm prints and the ten-finger palm prints, adding the field palm prints and the ten-finger palm prints to the client on an interface of the troubleshooting task, storing the field palm prints and the ten-finger palm prints into a directory corresponding to the troubleshooting task, and uploading the field palm prints and the ten-finger palm prints to the server.
The number of the live finger-palm prints and the number of the ten-finger-palm prints can be multiple.
104, after receiving the field palm prints and the ten-finger palm prints, the server correspondingly stores the field palm prints and the ten-finger palm prints and corresponding cases according to the case identification, and compares and checks the field palm prints and the ten-finger palm prints;
since there are one or more clients, the server may receive the case identifiers sent by multiple clients. Therefore, in order to avoid confusion, after receiving the field finger palm prints and the ten-finger palm prints, the server stores the field finger palm prints and the ten-finger palm prints in correspondence with corresponding cases according to the case identifications.
And after the server stores the field palm prints and the ten-finger palm prints, comparing and checking the field palm prints and the ten-finger palm prints. The server can compare the field finger and palm prints with the ten-finger and palm prints one by one. The server side can compare and investigate the field finger palm print and the ten-finger palm print by using an algorithm based on deep machine learning.
and the client side utilizes the interface provided by the server side to inquire and acquire a comparison and investigation result after the server side performs comparison and investigation. It can be understood that the case identifier may also carry an identifier of the client, and the server may also send a comparison and investigation result to the client after the comparison and investigation is completed.
And after the client side obtains the comparison and check result, determining the field fingerprint and palm print to be eliminated according to the comparison and check result. The comparison checking result includes information of whether the comparison is in the middle or not, for example, the comparison checking result can include two results of confirming the comparison in the middle or not. The client determines that the comparison and checking result is that the field fingerprint and palm print in the comparison is determined to be the field fingerprint and palm print needing to be excluded.
Compared with manual investigation, the technical scheme provided by the embodiment of the invention can help workers to perform on-site investigation with high speed, high precision and high intelligence. In the aspect of speed, taking 4-core single CPU as an example, one field fingerprint and palm print is compared with 1 person (10 fingers), and the method is improved from the fact that 1 time of examination is finished in the past to the fact that 40 milliseconds are required to finish one time of screening; in the aspect of precision, the comparison precision is improved over manual precision, and the comparison precision can be continuously improved by using artificial intelligence based on deep learning; meanwhile, compared with manual work, the problems of judgment errors and the like caused by visual fatigue due to workload can be avoided.
According to the embodiment of the invention, the client is used for sending the field finger palm print and the ten finger palm print corresponding to the case to the server for comparison and checking, and the field finger palm print needing to be eliminated is determined according to the comparison and checking result of the server, so that the automation of eliminating the owner and the finger palm print of the relevant person from the field finger palm print is realized, the efficiency of checking the finger palm print is improved, and the error rate is reduced.
Further, based on the above embodiment, the client queries and obtains a comparison and check result of the server, and determines the field fingerprint and palm print to be excluded according to the comparison and check result, which specifically includes: the client starts a timing check task, regularly inquires and acquires a comparison check result of the server, wherein the comparison check result comprises the information of the fingerprint and palm print identification; and updating comparison information according to the comparison and checking result, and determining the field fingerprint and palm print to be excluded according to the comparison information.
The client side inquires and obtains a comparison and check result of the server side, determines the field fingerprint needing to be eliminated according to the comparison and check result, and can be realized through a timing check task started by the client side.
The timing check task includes timing query and obtaining comparison check results of the server, for example, the timing check task may be set to perform query every 30 seconds. The client side obtains the comparison and investigation result of the server side without waiting for the completion of the investigation task, but can obtain the real-time comparison and investigation result according to the set timing period.
The comparison and checking result comprises the information of the finger and palm print identification, and the client can acquire the field finger and palm print or the ten-finger palm print stored by the client according to the finger and palm print identification, so that when the picture of the field finger and palm print or the ten-finger palm print needs to be displayed corresponding to the comparison and checking result of the finger and palm print, the server does not need to include the corresponding finger and palm print picture in the comparison and checking result, and only needs to include the information of the finger and palm print identification in the comparison and checking result.
Because the client can query and obtain the comparison and investigation result of the server at regular time, the obtained comparison and investigation result is the latest at each query moment. The client may perform corresponding processing on the finger and palm prints in the comparison and search result received earlier, for example, the comparison and search result may be subjected to live finger and palm prints removal. Therefore, the client does not synchronize the latest comparison and check result obtained from the server directly to the client, but updates the comparison information according to the comparison and check result at the client.
When the client acquires the comparison and investigation result from the server for the first time, the comparison information may be consistent with the comparison and investigation result; and the client side is used for updating the comparison information according to the comparison and investigation result obtained from the server side subsequently according to the timing period. For example, the new comparison and check result is added.
The client side queries the server side at regular time and acquires the comparison and investigation result due to one or more client sides, so that the pressure of the server side is greatly reduced, and the server side only needs to execute the investigation task and store the result; and after receiving a query request sent by a client, sending a corresponding comparison and checking result to the client.
On the basis of the embodiment, the embodiment of the invention regularly inquires and acquires the comparison and investigation result of the server, and updates the comparison information according to the comparison and investigation result, thereby improving the efficiency of checking the fingerprint and palm print and reducing the pressure of the server.
Further, based on the above embodiment, the comparison information includes one of three comparison results of confirmed comparison, possible comparison and no comparison corresponding to different field fingerprint; wherein, the field finger-palm print to be excluded is the field finger-palm print in the confirmation comparison.
The comparison information comprises one of three comparison results of confirmed comparison, possible comparison and no comparison corresponding to different field palm prints. Confirmation of the comparison, possible comparison and no comparison refer to three types of comparison results that may appear for a certain field fingerprint. Wherein, the "confirmation ratio in" indicates that the server determines the field finger-palm print ratio, for example, ten finger-palm prints with a similarity rate of 100%; "may be more than medium" means that the server side is regarded as being more than medium to a great extent, but is uncertain, such as a ten-finger palm print with a similarity rate of 90%; the 'unmatched' means that the server determines that the field palm print is unmatched, and the ten-finger palm print similar to the field palm print does not exist. Wherein, whether the judgment is similar or not can be judged through a threshold value.
The field fingerprint and palm print needing to be excluded is the field fingerprint and palm print in the confirmed comparison result. The comparison information comprises the comparison result of the possible comparison, and a foundation is laid for manual checking.
On the basis of the above embodiment, the embodiment of the present invention provides conditions for combining the results in the possible comparison with manual investigation by including three comparison results in the confirmed comparison, the possible comparison, and the non-comparison in the comparison information.
Further, based on the above embodiment, the comparison information is presented in a form of a list at the client, and for the comparison information in which the comparison result is a confirmation comparison and a possible comparison, a manual identification tag is set, the method further includes: entering a manual identification interface by clicking the manual identification label, and displaying a field palm print and a ten-finger palm print corresponding to the comparison information on the manual identification interface; setting the comparison result of the on-site fingerprint and palm print as a confirmation ratio by clicking a preset confirmation button; and setting the comparison result of the field fingerprint and palm print as a non-comparison result by clicking a preset cancel button.
And the comparison information is presented at the client in a list form. The comparison information may include a finger-palm print identifier of a field finger-palm print, and the finger-palm print identifier may be a symbol sequence; and includes the results of the alignment, i.e., one of the cases in the confirmed alignment, the possible alignment, and the no alignment. And for the comparison information in the confirmed comparison and the possible comparison, the comparison information also comprises the fingerprint and palm print identification of the corresponding ten-finger palm print.
And setting a manual identification tag for the comparison information in the confirmed comparison and the possible comparison, wherein the comparison information is the comparison information in the confirmed comparison and the possible comparison, and the method further comprises the following steps:
clicking the manual identification label to enter a manual identification interface, and displaying the field palm print and the corresponding ten-finger palm print on the manual identification interface; the pictures of the field finger-palm prints and the ten-finger-palm prints can be obtained by the client from the finger-palm print pictures stored by the client according to the finger-palm print identification.
And setting the comparison information of the field fingerprint and palm print as a confirmation comparison by clicking a preset confirmation button, such as a 'yes' button. And setting the comparison information of the field fingerprint and palm print as a non-comparison result by clicking a preset cancel button, such as a 'No' button. For example, after the information in the original comparison is the information in the comparison of "possible comparison in middle" or "confirmation comparison in middle", and the displayed field finger palm print and the ten finger palm print are manually checked, if the two are similar, the confirmation button can be clicked, and the comparison information is set as "confirmation comparison in middle"; if the two are not similar, a cancel button can be clicked, and the comparison information is set as 'not compared'.
For the information in the "no compare in" ratio, because the number is huge and the reliability of machine investigation is high, the manual identification label is not needed to be set.
On the basis of the above embodiment, the embodiment of the present invention sets the manual identification tag for the comparison information in the confirmation comparison and the possible comparison according to the comparison result, thereby realizing the combination of machine check and manual check, and further improving the reliability of the finger and palm print check.
Further, based on the above embodiment, the method further includes: and if the confirmation button or the cancel button is not clicked within the preset time after the comparison result is the comparison information in the possible comparison, automatically setting the comparison result in the comparison information as the non-comparison.
The function of manual qualification is provided, but does not indicate that the step of manual troubleshooting is necessarily performed. For example, if the operator does not have the capability of manual palm print screening, the result of machine screening can be directly adopted.
In order to improve reliability, within a preset time after the comparison information with the comparison result of "possible comparison" is generated, if the confirm button or the cancel button is not clicked, the comparison result in the comparison information is automatically set as "not compared". The client does not eliminate the field finger-palm print which is not compared, so that the client can continuously acquire and update the comparison and check result aiming at the field finger-palm print before the check task of the server is not finished.
And if the confirmation button or the cancel button is not clicked within the preset time after the comparison information of which the comparison result is 'confirmation comparison in middle' is generated, the comparison result of 'confirmation comparison in middle' is defaulted.
On the basis of the above embodiment, in the embodiment of the present invention, if the confirm button or the cancel button is not clicked within the preset time after the comparison result is the comparison information in the possible comparison, the comparison result in the comparison information is automatically set as the non-comparison, so that the flexibility and the practicability are improved.
Further, based on the above embodiment, the method further includes: if the server side judges that the execution of the troubleshooting task is finished, the troubleshooting engine is closed; the timing check task further comprises: and inquiring the execution state of the troubleshooting task of the server at regular time, and stopping executing the timing inspection task if the completion of the troubleshooting task is judged and known.
And after receiving the case identification sent by the client, the server starts a troubleshooting engine to execute a corresponding troubleshooting task, and inspects the sent field finger palm print and the ten finger palm print under the case. Although the server can execute the checking tasks in a multithread manner to meet the checking requirements of a plurality of clients, the computing capacity of the server is limited after all. If the server judges that the execution of the troubleshooting tasks of the corresponding case is finished, the server closes the troubleshooting engine.
When the server side runs in a multithread mode, the troubleshooting engine can be called in parallel to provide comparison troubleshooting service for each client side. When the server judges that the troubleshooting tasks of the corresponding cases are finished, and closes the troubleshooting engine, the server means closing the execution process of the troubleshooting engine called for executing the troubleshooting tasks of the corresponding client without influencing the comparison troubleshooting service of other clients.
The client regularly inquires and obtains a comparison checking result of the server by starting a regular checking task; meanwhile, the timing check task is also used for inquiring the execution state of the check task of the server at regular time, and if the completion of the execution of the check task is known by judgment, the execution of the timing check task is stopped. That is, the client does not need to query the server and obtain the comparison and investigation result after the investigation task is finished.
The timing inspection task started by the client can simultaneously inquire and acquire the comparison and investigation result of the server, inquire the execution state of the investigation task of the server, and stop the execution of the timing inspection task if the completion of the execution of the investigation task is known by judgment.
On the basis of the embodiment, the embodiment of the invention effectively saves the computing resources of the server and the client by closing the troubleshooting engine at the server when the acquisition of the troubleshooting task is finished and stopping the execution of the timing inspection task at the client.
Further, based on the above embodiment, the method further includes: adding the newly added field palm prints and/or ten-finger palm prints under the case by the client, and acquiring the state of the troubleshooting engine of the server; if the client side judges that the troubleshooting engine is in a closed state, the case identification is sent to the server side again, and the troubleshooting engine is restarted; after the troubleshooting engine is restarted or the client judges that the troubleshooting engine is in an open state, the client sends the newly added on-site finger palm print and/or the ten-finger palm print to the server; and after receiving the newly added field finger palm prints and/or the ten-finger palm prints, the server end adds the newly added field finger palm prints and/or the ten-finger palm prints into the troubleshooting task.
Adding field finger palm prints or ten finger palm prints at the client can be carried out in two ways. One method is that all field finger palm prints and ten finger palm prints under a case are added into a checking task by taking the case as a unit; in addition, because the field palm prints or ten-finger palm prints of a certain case can be obtained successively, single or multiple field palm prints can be added according to the query result from the external server; and the newly added field finger palm prints or ten finger palm prints under the case can be added to the client side in succession.
Because the server saves computing resources, after the troubleshooting task is judged to be finished (for example, the comparison between the field fingerprint and the ten-finger fingerprint sent under the corresponding case is finished, and a new fingerprint and palm print picture is not received within a certain time), the server closes the troubleshooting engine. In order to support the troubleshooting of the newly added field finger palm prints or the newly added ten-finger palm prints, after the newly added field finger palm prints and/or the newly added ten-finger palm prints under the case are added by the client, the state of a troubleshooting engine of the server is judged firstly.
And if the client judges that the troubleshooting engine is in a closed state, the case identification is sent to the server again, the troubleshooting engine is restarted, the newly added field finger palm print and/or the ten-finger palm print are sent to the server, and the newly added field finger palm print and/or the ten-finger palm print are added into the troubleshooting task after the server receives the newly added field finger palm print and/or the ten-finger palm print. For example, the newly added live finger print and all the ten-finger print (including the previously stored and newly added ten-finger print) are compared, and the originally stored live finger print and the newly added ten-finger print are compared and the like.
If the client judges that the troubleshooting engine is in an open state, the client directly sends the newly added on-site finger palm print and/or the ten-finger palm print to the server; and after receiving the newly added field finger palm prints and/or the ten-finger palm prints, the server end adds the newly added field finger palm prints and/or the ten-finger palm prints into the troubleshooting task.
On the basis of the embodiment, the embodiment of the invention improves the continuity, flexibility and practicability of the execution of the checking task under the single case by executing the checking task on the newly added field finger palm print and/or the ten finger palm print.
Fig. 2 is a schematic diagram of a method for eliminating the finger-palm prints of the owner and the relevant persons according to the embodiment of the present invention. As shown in fig. 2, the method includes:
and a new troubleshooting task is created at the client, a troubleshooting engine is started, and the troubleshooting task is executed.
Adding field fingerprint and palm print by the client, wherein the first method comprises adding single or multiple field fingerprint and palm print according to the query result; second, all the finger and palm prints under the case are added to the troubleshooting task in case units. The added live finger-palm prints (live cards) are stored in a live queue of the client. And after adding the field finger and palm print, the client uploads the field finger and palm print to the server.
And adding the palm print of the ten fingers by the client, and adding the palm print of the ten fingers of the owner and the related personnel into the troubleshooting task. The ten-finger palm prints (right-pressing printing cards) are stored in a right-pressing printing queue of the client. After the palm print of the ten fingers is added, the palm print is uploaded to the server side.
And obtaining the comparison result. When adding the field finger palm print or adding the ten-finger palm print, the client uploads the field finger palm print and the ten-finger palm print to the server at the same time, and the server automatically initiates a checking task on the received field finger palm print and the ten-finger palm print. The client starts a timing check thread, checks the task execution condition of the server according to a preset time period, and updates the task execution condition by acquiring a result of checking comparison (task result) and the state of the task (whether checking is finished). And if the client judges that the task execution of the server is finished, stopping the timing check. After the client side obtains the comparison and investigation result, the returned result can be inspected.
And checking comparison results. The comparison result has three states, and the compared result is the confirmed comparison result and the identity is confirmed; the possibility is larger than that the possibility is that the owner or related personnel are left behind and need to pay attention to confirmation; and the non-comparison is sent to the background for comparison, and the identity is required to be confirmed.
And (5) processing the artificial identification result. When the manual judgment is yes, the checking work of the palmprint of the finger is finished; and when the result is determined manually, the comparison result of the fingerprint and palm print is obtained again, and the comparison result can be checked with other follow-up personnel.
And when the field finger palm print is added again or the field finger palm print is added again, a checking task is also initiated aiming at the newly added finger palm print.
The fingerprint and palm print of the owner and the related people are eliminated. And eliminating the field fingerprint and palm print which is confirmed as the owner and the related person for a task, wherein the rest field fingerprint and palm print is the fingerprint and palm print needing to be screened.
And sending a background (storing a fingerprint and palm print library) for comparison. And sending the remaining unknown live finger-palm prints to a background for comparison, returning confidence values of corresponding finger-palm prints after background comparison, and performing identification according to returned results.
In the embodiment of the invention, manual inspection is replaced by a machine, so that the working efficiency is improved; in the process of investigation, a full-automatic tool is provided to energize field investigation personnel; a high-precision and quick troubleshooting algorithm is provided, and the fingerprints and palm prints of the owner and the related people are accurately identified; the efficiency of work is improved, the validity of investigation result is guaranteed, the work enthusiasm of on-the-spot investigation personnel is improved.
In the prior manual examination, a worker often judges through an image of a finger and palm print, which has great subjectivity, and in general finger and palm print comparison, the comparison can be performed after a field finger and palm print icon is manually marked with a characteristic.
The embodiment of the invention automatically extracts the characteristics of the ten-finger palm print and the field finger palm print, automatically compares the finger palm print with high precision, and automatically identifies the comparison result, thereby achieving the purposes of rapidness, precision and less manual intervention as possible; the working time of workers is reduced, and the working efficiency of the workers is improved. Meanwhile, compared with the traditional finger and palm print system, the embodiment of the invention can carry out comparison in an area range, input a personnel library (such as 10 persons) in a certain range, and then quickly compare the collected field finger and palm prints in a small library, thereby improving the comparison speed and quickly verifying related personnel.

the client 1 is used for newly building a troubleshooting task, the troubleshooting task corresponds to a case, and a case identifier of the troubleshooting task is sent to the server 2; adding field finger and palm prints and ten finger and palm prints to the server 2, wherein the field finger and palm prints are finger and palm prints acquired in a case scene, the ten finger and palm prints are finger and palm prints of an acquired owner and related persons, and the field finger and palm prints and the ten finger and palm prints carry corresponding finger and palm print identifiers and case identifiers; moreover, a comparison and checking result of the server 2 is inquired and obtained, and the field fingerprint and palm print needing to be excluded is determined according to the comparison and checking result; the number of the client sides 1 is one or more; the server 2 is used for starting a troubleshooting engine to execute a troubleshooting task after receiving the case identification sent by the client 1; and after the field palm prints and the ten-finger palm prints are received, correspondingly storing the field palm prints and the ten-finger palm prints and corresponding cases according to the case identification, and comparing and checking the field palm prints and the ten-finger palm prints.
A client 1 firstly creates a troubleshooting task, wherein the troubleshooting task corresponds to a case one by one; and after the investigation task is established, generating the case identification corresponding to the investigation task at the same time. And after the client 1 establishes the troubleshooting task, the case identification is sent to the server 2. The actual troubleshooting task is executed by the server 2; the number of the clients 1 is one or more, that is, the server 2 may serve a plurality of the clients 1 in a parallel manner.
After receiving the case identification sent by the client 1, the server 2 establishes a storage directory according to the case identification; meanwhile, starting a troubleshooting engine to prepare for executing a troubleshooting task. The live finger print and the ten-finger print can be obtained from an external server by using a data interface. The on-site finger-palm prints refer to finger-palm prints acquired in a case scene, and the ten-finger-palm prints refer to collected owner and finger-palm prints of related people; the field finger palm prints and the ten-finger palm prints can be collected by image collecting equipment and then stored in the external server.
After the client 1 acquires the field palm prints and the ten-finger palm prints, the field palm prints and the ten-finger palm prints are added to the client 1, can be stored in a directory corresponding to the troubleshooting task, and are uploaded to the server 2. The number of the live finger-palm prints and the number of the ten-finger-palm prints can be multiple. And after receiving the field palm prints and the ten-finger palm prints, the server 2 correspondingly stores the field palm prints and the ten-finger palm prints and corresponding cases according to the case identification. And after the server 2 stores the field palm prints and the ten-finger palm prints, comparing and checking the field palm prints and the ten-finger palm prints. The server 2 can compare the field finger and palm prints with the ten finger and palm prints one by one.
The client 1 uses the interface provided by the server 2 to query and obtain the comparison and investigation result after the server 2 performs comparison and investigation. And after the client 1 acquires the comparison and check result, determining the field fingerprint and palm print to be eliminated according to the comparison and check result. The comparison checking result includes information of whether the comparison is in the middle or not, for example, the comparison checking result can include two results of confirming the comparison in the middle or not. The client 1 determines that the comparison and checking result is that the field fingerprint and palm print in the comparison is determined to be the field fingerprint and palm print needing to be excluded.
According to the embodiment of the invention, the client is used for sending the field finger palm print and the ten finger palm print corresponding to the case to the server for comparison and checking, and the field finger palm print needing to be eliminated is determined according to the comparison and checking result of the server, so that the automation of eliminating the owner and the finger palm print of the relevant person from the field finger palm print is realized, the efficiency of checking the finger palm print is improved, and the error rate is reduced.
Further, based on the above embodiment, when the client 1 is configured to query and obtain a comparison and check result of the server, and determine the field fingerprint to be excluded according to the comparison and check result, the client is specifically configured to: starting a timing check task, regularly inquiring and acquiring a comparison check result of the server 2, wherein the comparison check result comprises the information of the fingerprint and palm print identification; updating comparison information according to the comparison and checking result, and determining the field fingerprint and palm print to be excluded according to the comparison information; wherein, the comparison information comprises one of three comparison results in a confirmed comparison, a possible comparison and a non-comparison; the field fingerprint and palm print needing to be excluded is the field fingerprint and palm print in the confirmed comparison result.
The client 1 queries and acquires the comparison and check result of the server 2, determines the field fingerprint and palm print to be eliminated according to the comparison and check result, and can realize the timing check task started by the client 1. The timing inspection task comprises timing inquiry and acquisition of a comparison and inspection result of the server 2. The client 1 obtains the comparison and investigation result of the server 2 without waiting for the completion of the investigation task, but can obtain the real-time comparison and investigation result according to the set timing period.
Because the client 1 can query and obtain the comparison and check result of the server 2 at regular time, the obtained comparison and check result is the latest at each query moment. When the client 1 acquires the comparison and investigation result from the server 2 for the first time, the comparison information may be consistent with the comparison and investigation result; the client 1 is used for updating the comparison information according to the comparison and investigation result subsequently acquired from the server 2 according to the timing period.
The comparison information comprises one of three comparison results of confirmed comparison, possible comparison and no comparison corresponding to different field palm prints. Confirmation of the comparison, possible comparison and no comparison refer to three types of comparison results that may appear for a certain field fingerprint. Wherein, the "confirmation ratio in" indicates that the server 2 determines the field palm print ratio; "may be more than medium" means that the server 2 is considered to be more than medium to a greater extent, but is uncertain; "unmatched" means that the server 2 determines that the field palm print is unmatched, and there is no similar ten-finger palm print to the field palm print. The field fingerprint and palm print needing to be excluded is the field fingerprint and palm print in the confirmed comparison result.
On the basis of the embodiment, the embodiment of the invention improves the efficiency of checking the fingerprint and palm print and reduces the pressure of the server by regularly inquiring and acquiring the comparison checking result of the server and updating the comparison information according to the comparison checking result; by including three comparison results in the confirmed comparison, the possible comparison and the non-comparison in the comparison information, conditions are provided for combining the results in the possible comparison with manual investigation.
Further, based on the above embodiment, the client 1 is further configured to add a newly added field fingerprint and/or ten-finger fingerprint under the case, and acquire the state of the troubleshooting engine of the server 2; if the client 1 judges that the troubleshooting engine is in a closed state, the case identification is sent to the server 2 again, and the troubleshooting engine is restarted; after the troubleshooting engine is restarted or the client 1 judges that the troubleshooting engine is in an open state, the client 1 sends the newly added on-site finger palm print and/or the ten-finger palm print to the server 2; and the server 2 is further configured to add the newly added field palm prints and/or the newly added ten-finger palm prints into the troubleshooting task after receiving the newly added field palm prints and/or the newly added ten-finger palm prints.
Adding a field finger palm print or a ten-finger palm print at the client 1 can be carried out in two ways. One method is that all field finger palm prints and ten finger palm prints under a case are added into a checking task by taking the case as a unit; in addition, single or multiple field palm prints can be added according to the query result from the external server; and the newly added field finger palm prints or ten finger palm prints under the case can be added to the client side in succession.
Since the server 2 saves computing resources, the troubleshooting engine can be shut down after the troubleshooting task is judged to be finished. In order to support the troubleshooting of the newly added field palm prints or ten-finger palm prints, after the newly added field palm prints and/or ten-finger palm prints under the case are added by the client 1, the state of the troubleshooting engine of the server 2 is firstly judged.
If the client 1 judges that the troubleshooting engine is in a closed state, the case identification is sent to the server 2 again, the troubleshooting engine is restarted, the newly added field finger palm print and/or the ten-finger palm print are sent to the server 2, and the newly added field finger palm print and/or the ten-finger palm print are added to the troubleshooting task after the server 2 receives the newly added field finger palm print and/or the ten-finger palm print.
If the client 1 judges that the troubleshooting engine is in an open state, the client 1 directly sends the newly added on-site finger palm print and/or the ten-finger palm print to the server 2; and after receiving the newly added field palm prints and/or the ten-finger palm prints, the server 2 adds the newly added field palm prints and/or the ten-finger palm prints into the troubleshooting task.
